Laparoscopic instrument to perform fundoplication in esophageal reflux surgery

  • Medical devices

Gastroesophageal reflux disease occurs when the lower esophageal sphincter (LES), the valve in charge of controlling the passage of contents from esophagus into the stomach, is altered or inappropriately relaxed, allowing the content to revert to the esophagus, irritating its mucous membrane.

The surgical treatment of this disease is performed laparoscopically using a specific technique named as Nissen technique , which involves passing the fundoplication behind the esophagus, facilitating the function of closing the lower esophageal sphincter (LES) and making it difficult for the stomach’s contents to return to the esophagus.

The biggest difficulty in this type of intervention is to pass the gastric fundus (GF) through the retroesophageal tunnel. Also, the use of straight tweezers is complicated to reach the gastric fundus (GF), and it also makes it difficult to grasp with tweezers, which are not firm enough to perform the traction.

All these facts above mentioned force to start the operation again. To improve this maneuver, a new laparoscopic device has been designed by this researcher, which fixes the aforementioned problems.

The mentioned instrument has been designed with two variants, one rigid and one flexible, in which the same maneuver is performed. Both are comprised of a rod with a drive mechanism at the proximal end of the instrument for the purpose of bending a portion at two points. So, it is possible to alternate between a straight or curved configuration to improve with confidence the maneuver of moving the gastric fundus (GF) through the retroesophageal tunnel.


  • At the moment there are no alternative products that allow to perform the maneuver in an easier way, thus avoiding possible related problems, especially in certain surgeries with singular complexity.

  • It consists in an improved device with great utility, providing greater effectiveness, low economic cost, easy handling and low technical difficulty.
